Wall print file size

[Anthony Glick]

Hi there, 

I have a customer who is printing one of my images up on wall paper for a wall piece. 

the final size will be 282cm wide and 262cm high. 

I need to get the file ready for print but I am not sure how to export?

The wallpaper supplier is telling me I need to have an absolute minimum of 72 DPI in reference to the wall dimensions. I am not sure how to properly export this from lightroom? If anyone can offer any assistance that would be greatly appreciated!

Do you know if they need bleed?  Or is this the exact size of the file they need?

Hi Damien,

 

They want the file ready for print. 

 

Cheers

I know, but if 282*262 is the size of the wall, is that the size of the file they need? Or do they need a few cm extra for bleed or trimming?

[Anthony Glick]

no need for bleeding or trimming. Thanks

[Damien Symonds]

Terrific!

So all you need to do is open the photo in Photoshop, choose your crop tool, and enter the values they've given you:

When you crop it, it will enlarge a LOT on your screen.  That's a good thing.

Then when saving the jpeg, choose 7 on the 0-12 quality scale.  That will give ample quality, but keep the file manageably small.  (Oh, and make sure you choose "Baseline Standard" in that window also).

Thank you so much for your help. I had a bit of trouble completing the process in photoshop so I saved it and it went to my lightroom and then I exported it. 

Does this look okay?

I am worried about the RGB colour space? Although the colour profile is SRGB?

 

Confusing stuff mate, cheers for helping me out. 

[Damien Symonds]

Yes, that all looks right.  What did you choose on the 0-100 scale for the quality of the save?

[Anthony Glick]

In lightroom 100%

Oh no, no wonder it's so darn big! PLEASE start using real software.

In the meantime, re-export it at 60 quality.
